ADAPTABLE COMMUNICATION SENSITIVITY FOR AN IMPLANTABLE MEDICAL DEVICE - A wireless communication threshold for an implantable medical device is automatically adapted in an attempt to maintain optimum signal detection sensitivity. In some aspects, a threshold level may be adapted to account for current environmental conditions, implant conditions, device conditions, or other conditions that may affect the reception of wireless signals at the device. In some aspects, the determination of an optimum level for the threshold involves a tradeoff relating to effectively detecting target signals while avoiding detection of noise and/or interference. In some aspects, adaptation of a threshold may be based on maximum energy levels associated with one or more sets of RF energy sample data. In some aspects, adaptation of a threshold may be based on the number of false wakeups that occur during a period of time.

ADAPTIVE STAGED WAKE-UP FOR IMPLANTABLE MEDICAL DEVICE COMMUNICATION - A communication wake-up scheme for an implantable medical device may involve repeatedly activating a receiver to determine whether an external device is attempting to establish communication with the implantable device. To reduce the amount of power consumed by the implantable device in conjunction with the wake-up scheme, the scheme may involve conducting preliminary RF signal detections as a precursor to conducting a full scan. In this way, power may be conserved since the more power intensive full scans may be performed less frequently. This preliminary detection of RF signals also may be adapted to reduce the number of full scans performed by the implantable device that do not result in communication with the external device. In some embodiments the adaptation involves adjusting one or more thresholds that are used in conjunction with the preliminary detection of RF signals. In some embodiments a wake-up scheme may involve scanning for signals using an initial RF band that is relatively wide, and then scanning for signals using narrower RF bands.

Controlled bending of pipeline by external force - Controlled bending of a pipeline laying on the sea floor is achieved by attaching a bending sleeve assembly to a selected bending zone of the pipeline for limiting the controlled bending of the pipeline to a predetermined resulting bending configuration. External force is then applied on the bending sleeve assembly, bending the pipeline to the predetermined resulting bending configuration in cooperation with the bending sleeve assembly and the sea floor. External force can be exerted from one or more weights placed on top of the bending sleeve assembly. External force can be exerted from a winch attached to a wire, the wire passing through a pulley attached to a fixed structure, and the wire attached to the bending sleeve assembly. External force can be exerted through the bending sleeve assembly's contact reaction with an immobile object.

Improved Subsea Riser System - An improved riser system which comprises a connector for connecting conduits and a mooring system for mooring the connector to the floor of a body of water. The improved riser system also comprises a buoy system for supporting the connector. The buoy system is configured to provide a fixed buoyancy for the connector, the mooring system and at least a portion of the conduits and for providing variable buoyancy for placement of the connector at a predetermined water depth.

BENDING RESTRICTOR ASSEMBLY FOR USE WITH A PIPELINE SECTION - A bending restrictor assembly for use with a pipeline section has a sleeve affixed to the pipeline section, an outer collar slidably positioned relative to and over the sleeve, and an inner collar slidably positioned relative to an interior of the outer collar. The inner collar in spaced longitudinal relation to an end of the sleeve. The inner and outer collars are slidable relative to a bending of the pipeline section. A series of holes and keyways are formed in the inner and outer collars. Pins are inserted into corresponding holes and keyways so as to correspond to a limit of the bending radius of the pipeline section.
